Susien,
We're a family of 5, 2 ads, 1 teen, a 12 yr old & a 10 yr old. Like you we hate fake designer stuff! Took £1500 for 2 wks, ate out every night with snacks during day, fair bit to drink in the evenings, did 4 trips & brought little back (just a few towels, bits n pieces for kids friends, turkish delight etc).
Had a brill time, came back with 5 lira!
Hope that gives you an idea.
